The Parisian club has now claimed the prestigious cup on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a successful spot-kick decider to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side fired twice late to seize a surprise advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for PSG to seal a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past thirteen seasons.
